Handoff: Metroid Prime Hunters Wi‑Fi Probe / Connection Stuck Work

Current state

  • Active repo: F:\Projects\ndsrecomp\metroidprimehuntersrecomp-live-overlay-provider
  • Active branch pushed: codex/watchdog-fix-20260817
  • Latest commit: 4a63af6
    • Message: Harden MPH Wi-Fi probe summary and runner help parsing
    • Pushed to origin.

What was done

  • Previously implemented scripts in this repo to automate MPH WFC flows:
    • tools/probe_mph_wfc.py (setup/search/friends/finding game automation)
    • tools/probe_nodump_wfc_auth.py
    • tools/run_mph_wfc_instances.py
  • In 4a63af6 fixed robustness issues in probe_mph_wfc.py:
    • --help output parsing in _runner_help_mentions now captures stderr too.
    • Summary path no longer crashes when counts entries are missing.

Most important files touched

  • tools/probe_mph_wfc.py

Latest test outcomes (important)

  • Multiple scripted runs of probe_mph_wfc.py for:
    • --flow setup
    • --flow search-game
    • --flow friends-rivals
  • Runner: F:\Projects\ndsrecomp\ndsrecomp\runner\build-mph-release\nds_runner.exe
  • Backend: --network-backend slirp, --wfc-provider wiimmfi

Observed result:

  • Runs complete through menu flow but report as *_no_network:
    • dhcp = 0
    • dns_query = 0
    • tcp_open = 0
    • tls_record = 0
    • backend_error = 0
    • backend_drop = 0
  • In all failing scripted runs, net_state still reports:
    • wifi_attached: True, network_enabled: True
    • backend: slirp, live_backend_active: True, worker_active: True
    • wfc_dns_ip resolved to 178.62.43.212.

No successful authenticated/network event capture was observed in probe outputs.

Key evidence files

  • Run outputs under:
    • F:\Projects\ndsrecomp\scratch\wifi-stability\run01
    • ...\run05, run07, run08, run12
  • Prior successful-looking manual-auth artifacts may still be in:
    • F:\Projects\ndsrecomp\metroidprimehuntersrecomp\scratch\nodump-wfc-20260814\

Commands used

  • Test command pattern: 
    py -3 tools/probe_mph_wfc.py `
  --runner F:\Projects\ndsrecomp\ndsrecomp\runner\build-mph-release\nds_runner.exe `
  --rom F:\Projects\ndsrecomp\metroidprimehuntersrecomp\Metroid Prime Hunters.nds `
  --config F:\Projects\ndsrecomp\metroidprimehuntersrecomp\game.toml `
  --out <outdir> `
  --save-path F:\Projects\ndsrecomp\metroidprimehuntersrecomp\scratch\nodump-wfc-20260814\nodump.sav `
  --port 199xx --instance-index 1 `
  --flow <setup|search-game|friends-rivals> `
  --network-backend slirp --wfc-provider wiimmfi `
  --connection-timeout 35 --connection-stall-s 10 --startup-mode automatic
  • --no-dumps mode tested too (with default profile path generation).

Known probable blocker to continue

  • The probe automation reaches menus and confirms backend state, but no actual WFC net events are recorded.
  • This suggests the game may be blocked before issuing any socket/dns/tcp activity in this scripted input path, likely one of:
    1. missing/incorrect interaction path in automated taps for this specific session state,
    2. stale profile/save/firmware state assumptions differing from manual flow,
    3. no network events emitted until a later in-flow step that automation exits too soon.

Suggested continuation plan for Fable

  1. Replay same session in manual UI and capture exact input deltas with screenshots from a known-working run.
  2. Confirm probe_nodump_wfc_auth.py/probe_mph_wfc.py tap sequence matches that exact flow.
  3. Dump net_state + net_progress + ring every step, especially right when entering test/confirm dialogs.
  4. Compare successful manual save/firmware against script-generated ones:
    • try using the exact save/firmware from manual connect as --save-path and --firmware-state-path inputs
  5. Add explicit ring query for dhcp before/after each screen transition and fail-fast only if no possible state-change evidence for N+ seconds.
  6. If automation still gets no events, validate whether game is waiting in a modal/UI state by adding stronger image-based screen-state checks.

Note

  • There is an untracked bios/ folder in this worktree from local runs. It is not part of this commit.
  • Latest run logs include runner.stderr.log showing backend initialized cleanly, no runtime errors.
